The fact is all mobile phases contain some chemical contaminants or microparticulates, from the sample, solvent, or wear on the polymeric seals of the pump or injector. These contaminants can clog frits, irreversibly bind to an HPLC column, degrade performance, and even damage the flow cell. SecurityGuard™ is a universal HPLC guard cartridge system designed to effectively (and inexpensively), protect all your valuable analytical columns from the damaging effects of chemical contaminants, without altering your chromatographic results.

"SecurityGuard offers a convenient and economical way to extend HPLC column lifetimes. It is effectively designed to eliminate carryover contamination which is the common cause of high backpressure, split peaks, broad peak, baseline noise and loss of valuable resolution. Such system works to trap any contamination from passing to the HPLC column; thus it can extend the lifetime of HPLC columns and result in better chromatography. It is very easy and simple to install and handle."
